It is true that the software compatibility is an issue for developers. However ultimately, developers will invest for the hardware the gamers are using. I am a hard core gamer. I use a PC for gaming and a Mac for everything else. Raw GPU performance is still inferior on Mac. Mac are very efficient, PC are not. NVidia is overclocking like hell their GPUs: laptops would drain their battery in minutes if not plugged-in and on the desktop side, they are talking of using two 120V 15A circuits (3,600W potentially) to feed your computer and a big part of the high end is water cooled at least for those that mind the noise generated by all the fans trying to cool everything down. From the benchmarks I have seen, MacBooks seems to sip up to 50W in power mode and desktops about 100W, so the efficiency crown goes to Apple hands down.

Mac are slim, cool and noiseless. PC are bulky, hot and noisy. But gamers do not care about that, they just want raw power, the more the better. And Mac still don't support ray tracing in hardware, honestly not many games support raw tracing, but you know the fear of missing out is strong for many gamers. Furthermore, because of the overclocking, an inexpensive gaming PC GPU will usually outperform a Mac GPU, Mac are still perceived to cost too much for what you get.

So the alignment between Apple philosophy and the gamers is not great. Gaming will always be marginal on Mac, and limited to the people already owning a Mac. The only segment, Apple hardware will put them ahead is mobile gaming. iPhone and iPad fill the needs for casual gamers in this segment, but their is no dedicated game devices for serious gamers like the Steamdeck, and I don't think Apple wish to enter this market either.
